Answer:
Median highland = 16 mm
Median lowland = 16 mm
Step-by-step explanation:
For the highland area :
The sample size, n = 44
Obtain the median value using :
1/2 * (n + 1)th term
1/2 * (44 +1) th term
1/2 * 45 = 22.5th term.
(22nd + 23rd) term / 2
(16 + 16) / 2 = 16 mm
For the lowland area :
1/2 * (n + 1)th term
1/2 * (44 +1) th term
1/2 * 45 = 22.5th term.
(22nd + 23rd) term / 2
(12 + 12) / 2 = 12 mm
Answer:
Step-by-step explanation:
n, n+2, n+4
2(n+2)-n=11
2n+4-n=11
n+4=11
n=7
So the three consecutive odd terms are 7, 9, 11.
The answer is 25:1 or 25 to 1. They are the same thing thought.
Answer:
<h2>M(-a, b)</h2>
Step-by-step explanation:
Use the formula of a midpoint:
We have the points P(-2a, 0) and Q(0, 2b). Substitute:
